A supernova represents the spectacular explosion of a star, marking one of the most energetic events in the universe. Fusion continues in layers like an onion, creating iron in the core.
Simple Definition Supernova Galaxy Impact
If this white dwarf exists in a binary system, it can siphon material from a companion. This collapse rebounds off the dense core, generating a shockwave that expels the outer layers into space.
This process generates an outward pressure that balances the inward pull of gravity. Such observations provide critical data on the distribution of heavy elements throughout the galaxy.
